A liquid leakage hole 2252 is formed inside the boss 2251 when viewed from the inside and outside of the vehicle, and the outer surface of the boss 2251 does not contact the inner surface of the third connection plate 215 at the fifth connection sub-plate 225, and a gap exists therebetween, which may correspond to the liquid leakage hole 2252. The weep hole 2252 is located vertically and communicates with the sill inner cavity when viewed from above and below the vehicle, so that after liquid flows into the sill inner cavity, the liquid flows downward from above and then out of the vehicle through the weep hole.
In an alternative embodiment of the application, the boss 2251 has a cross-sectional shape of one of a circle, a semicircle and a rectangle, and the cross-sectional shape of the weep hole 2252 is adapted to the cross-sectional shape of the boss 2251.
Specifically, as shown in fig. 3, the cross-sectional shape of the boss 2251 is rectangular (may be seen as a strip), and in order to make the leak hole 2252 relatively large as much as possible, the cross-sectional shape of the leak hole 2252 is adapted to the cross-sectional shape of the boss 2251, and the cross-sectional shape of the leak hole 2252 is also rectangular, but of course, the cross-sectional shape of the boss 2251 may be circular, semicircular, or rectangular, and the cross-sectional shape of the boss 2251 is not limited in this embodiment, and the cross-sectional shape of the leak hole 2252 may be adapted to the cross-sectional shape of the boss 2251.
